MACHINE FOR COAL-BREAKING.

SPECIFICATION forming part of Letters Patent No. 707,945, dated August26, l1902.

Serial No. 68,376. (No model.)

T0 @ZZ wwnt it may concern:

Be it known that I, LON DE BERTIER DE SAUVIGNY, a citizen of France,residing at 17 Rue St. Marc, Paris, France, have invented cert-ain newand useful Improvements in Ma-V chines for Coal-Breaking and the Like,of which the following is a specification.

This invention relates to machines for breaking coal, coke, and similarsubstances, it being adapted especially for the working of coal andbeing adapted to effect large savings in coal.

The principle of the machine consists in breaking each piece of coal bythe action of two picks or points set opposite to each other and havingan alternate approaching and receding motion, in combination with asystem of prisms or prismatic roller-jaws movable about their axes andintended to retain each piece of coal until it has been subjected to theaction of the picks. These prisms or jaws ought to remain iixed duringthe time that the picks are penetrating the coal, and they ought tocommence to move immediately thereafter in order to permit the descentof the pieces of coal of the desired size. Acertain number of sets ortiers of working parts, each consisting of a series of prism-jaws andtwo series of picks, are superposed above each other, so that the piecesproduced by one set are brought under the action of the lower set.

The present invention has for its object a practical industrial machinein which certain existing defects have been carefully eliminated, aswill now appear. y

Figure l is aver-tical transverse section on the axis of the machine,taken on the line A B of Fig. 2. Fig. 2 is a plan. Fig. is a section onthe line C D of Fig. l. Fig. 4 is a side elevation. Fig. 5 is a frontview.

The machine consists of a body or frame a, formed in two parts,placedone on the other. The upper part forms the hopperb, into which the coalto be broken is emptied and from which it falls onto the rst tier or setof oscillatory rectangular prisms (hereinafter termed jaws) cand d, Fig.3. Thesejaws are actuated simultaneously approximately a distanceequaling the one-eighth part of a circle,which is communicated to theminthe mannerhereinafterdescribed. From thisitresults that the section ofthe passage or opening left between the jaws keeps varying constantly,being at a minimum when the jaws occupy the position shown in Fig. 3(upper set) and at a maximum when each prism has turned throughforty-five degrees, so that the upper faces become horizontal, as shownin the lower set of parts in Fig. 3. This last section is so calculatedas to only allow the mediumlsized and small pieces of coal to pass andto retain the large pieces until they have been submitted to the actionof the picks. The medium-sized and small pieces on leaving the uppertier fall upon a sieve c, which allows the small ones to pass andconveys the medium-sized ones into the second tier onto the set of jawsf and g, which are of smaller dimensions and closer together than thoseof the other tier. The small' pieces which are allowed to pass throughthe sieve c fall onto an inclined plate, which discharges them from themachine. The arrangement of the successive tiers in echelon oralternating, with the interposition between each pair of consecutivetiers of a sieve e, has the effect of withdrawing or eliminating thirtyper cent. of the coal without its passinginto the lower tiers.

Parallel to the axes of the jaws and situated a little above them arethe picks t, arranged two and two in line with each other and theirpoints facing each other. These picks are each tiXedon a slide, such as7c, there being one set of picks for one set of jaws; the machine showntherefore allowing of four slides 7c m n o, which work in suitableguides arranged in the frame a. At each of their extremities theseslides carry a pivot to which is coupled a link p q r s. These are intheir turn coupled to the extremities of two rocking levers t u, workingon pivots fu and w, carried by the frame a,Fig. l. The rocking levers ateach side of the machine are connected to one another by a link 00, andthe lever t is actuated by a link y, securedto a crank c', carried bytheshaft 1. This shaft extends along the whole length of the machine andreceives its movements from the pulley 2. An inspection of Fig. 2 willshowthat under these conditions the two slides 7o and m will advance orapproach each other while the two slides n and o are receding from eachother. It is the advancing movements of the IOO slides, and hence of thepicks, which effect the breaking or disintegration of the coal. Themovement of the jaws through the oneeighth part of a circle in thedirection required is communicated to said jaws in the following manner:On the axis of each of the upper jaws is keyed a crank-arm 3, the eX-tremity of which is coupled to a controllingrod 4 or 5, as the case maybe, the jaws c being coupled to the rod 4, while the jaws d are coupledto the rod 5. The rod 4 itself actuates the rod 5, through the medium ofa reversing-link 6, such that the two' rods are displaced in oppositedirections. The rod 4 receives a reciprocating motion from a bellcranklever 7, coupled bya link 8 to another bell-crank or like lever 9, Fig.4, which is actuated by a cam 10, keyed on the drivingshaft 1. On theother side of the machine is situated an identical arrangement foroperating the jaws fand g through the medium of the rods 11 and 12.

The picks t' are fixed on their respective slides lo m n o by the aid ofstirrups 13, tightened or clamped by means of screws 14, Fig. 1.

The jaws c clfg are slotted or divided parallel to their axes and areixed on the latter by means of clamping-bolts 15, Fig. 3. As each twoconsecutive prisms turn in opposite directions, it should be arranged tohave the breakage take place between the prisms pair by pair, to insurewhich the corresponding spaces or intervals are closed by the aid ofhinged covers 16,- Figs. 1 and 3.

From the preceding description it will be evident that my machineincludes jaws arranged in pairs, picks arranged in pairs adapted totravel toward and from each other, and mechanism for cordinatelyreciprocating the picks and oscillating the jaws.

The action of the machine is as follows: Assuming the parts to be in theposition shown in the drawings, the rotation of the crank-arm .2' bringsabout the advance or approach of the upper picks and the retirement orseparation of the lower ones. During this time the cam 10 keeps theupper jaws stationary, While the corresponding cam imparts to the jawsof the lower set their movement of one-eighth of a turn. When the cranka has traveled through one hundred and eighty degrees, the parts are allreturned to the position indicated in the drawings. As it continues itsmovement the upper picks become separated and the upper jaws commencetheir turning movement, while the lower picks commence to approach andtheir corresponding jaws become iiXed. It is absolutely necessary thatthe jaws should be brought to a stop while the picks penetrate the coalto be broken.

What I claim is- 1. A machine of the class described including aplurality of superposed jaws arranged in pairs, means for actuating saidjaws, picks also arranged in pairs and adapted to coact with therespective pairs of jaws, means for -fine material from the coarse andto direct the latter to the lower jaws.

3. A machine of the class described including a plurality of superposedjaws arranged in pairs, means for actuating said jaws, picks alsoarranged in pairs and adapted to coact with the respective pairs ofjaws, means for actuating the picks, a sieve adapted to receive thecrushed material from the upper jaws and serving to separate the finematerial from the coarse and to direct the latter toward the lower jaws,and means bridging the adjacent jaws of the respective pairs to preventthe passage of material therebetween.

4. A machine of the class described including jaws arranged in pairs,picks arranged in pairs adapted to travel toward and from each other,and mechanism for cordinately reciprocating the picks and oscillatingthe jaws.

5. A machine of the class described including jaws arranged in pairs,picks arranged in pairs adapted to travel toward and from each other,mechanism for cordinately reciprocating the picks and oscillating thejaws, and means for bridging the jaws of the respective pairs t-oprevent the passage of material between the same.

6. A machine of the class described including a plurality of superposedoscillatory jaws, picks also arranged in pairs to coperate with therespective pairs of jaws, a sieve arranged to receive the crushedmaterial from the upper jaws and serving to separate the fine materialfrom the coarse and to direct the latter toward the lower jaws, andmechanism for oscillating the upper and lower jaws in oppositedirections and for simultaneously reciprocating said picks in oppositedirections. l

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
